The hype over The Martian passed me by. If it hadn't, then I wouldn't have read this. Having read this, I shan't be reading any other Andy Weir books in the immediate future. There is the kernel of a good book in here, but it's ruined - for me - by firstly, excessive attention to detail. It's the textual equivalent of one of those less interesting Star Trek TNG episodes where the crew encounter a Problem which is eventually solved by the appliance of science. Sadly, the Enterprise crew were far more engaging than the underdeveloped protagonist here who is merely seems a frame on which to hang calculations. Secondly, Weir's problem solving is at his strongest when examining physical & engineering problems, but the biological nature of the Problem I found a bit silly. Thirdly and this is a problem that extends to a lot of science fiction, Weir's aliens are not particularly alien and the shared techbro sense of humour is risible. Not my cup of tea, but I can appreciate how other readers might find this very enjoyable.
